Abstract:
Free space optics system(FSO) is significantly degraded by attenuation under dif ferent climatic conditions. An FSO transmission system with high-speed transmission
capability is proposed by hybridization of PDM with CO-OFDM .The m-ary modu lation scheme like 4-QAM analysis were obtaining. The impact of different climatic
condition on system performance is investigated. Though simulations briefly explains
the 100Gbps 4-QAM information transmission at 0.5km.The proposed system reduces
channel fading,improves information rate,maximum transmission distance. This work
is considered as future FSO system in adverse climatic conditions.
